Jones’s ancestor Bryan Jones (d. 1681), a Welshman, settled in Dublin in the early seventeenth century. Bryan’s grandson Theophilus (1666-1742) of Headford, county Leitrim, sat for Sligo and county Leitrim in the Irish Parliament for a total of over 40 years. His grandson, another Theophilus (1729-1811), who married a Beresford, represented his native county as well as Coleraine and Monaghan at Dublin, 1761-1800, and county Leitrim at Westminster, 1801-2. His eldest son Walter (1754-1839), governor of Leitrim, was Member for Coleraine in both Parliaments in three spells between 1798 and 1809, while his second son Theophilus (1760-1835) served in the navy, becoming an admiral in 1819.
Jones entered the navy on 1 June 1803, serving as a first class volunteer in the Melpomone frigate, and the following year he was twice engaged as a midshipman in the bombardment of Le Havre. From November 1805 he served with his stepmother’s brother Henry Blackwood in the Euryalus, and they were both on board the Ajax when it caught fire and exploded near the island of Tenedos on 14 Feb. 1807. He subsequently joined the Endymion, seeing action in the Dardanelles, and after a period in England, he was appointed to the Warspite under Blackwood in May 1808. Commissioned as a lieutenant in July 1809, he served in the skirmish with the Toulon fleet in July 1810, and in home waters until 1814. He went with the convoy to the Cape in the Désirée, returning to Britain the following year to find himself again promoted. Having commanded the Cherokee on the Leith station from February 1819 till at least 1822, he was in May 1827 made second captain of the Prince Regent, which for a while was Blackwood’s flagship at the Nore. By the duke of Clarence, briefly lord high admiral, he was awarded the rank of captain, 25 Aug. 1828, but thereafter never again served at sea.
A second cousin of the underage 3rd marquess of Waterford, Jones was in late 1829 considered by the family managers as a possible candidate to replace the now pro-Catholic George Dawson on their interest in county Londonderry. Henry Barré Beresford observed that ‘I would think Theophilus Jones, as better known, would answer better than his brother’, but considered that the ‘Joneses are natives of Derry, well known and well liked and in certain parts of the county where they reside could gain many freeholders’.
his speech was much approved. The uproar was great when he said he would have voted against the Roman Catholics [emancipation] bill, but it was from the lowest mob. His conduct is much approved by all and I have no doubt he will be a useful working man, diligent and persevering.Belfast News Letter, 20 July, 20 Aug. 1830; Pack-Beresford mss A/190.
Jones was expected to be ‘pro-government’, but Planta, the Wellington government’s patronage secretary, listed him among the ‘moderate Ultras’ that autumn. He was noted as absent from the division on the civil list, 15 Nov. 1830, which led ministers to resign, though at the following election he asserted, apparently in vindication of his having divided with them on this occasion, that considerable economies had been made under the Tories.
He attended the meeting of Apprentice Boys in Londonderry, 26 Jan. 1831, when resolutions were passed against repeal of the Union.
He voted against the second reading of the revised reform bill, 17 Dec. 1831, and its committal, 20 Jan. 1832. Although he was in the majority against limiting the polling in boroughs of fewer than 1,200 voters to one day, 15 Feb., he voted against the enfranchisement of Tower Hamlets, 28 Feb., and the third reading, 22 Mar. He divided against Hunt’s motion for information on military punishments, 16 Feb. He brought up a petition for continuation of the grant to the Kildare Place Society, 23 Feb., and another against the government’s plan for national education in Ireland, 8 Mar.; he denied that his opposition to the latter was political, 16 Mar. He supported the city petition for alteration of the grand jury laws, 5 Mar., and defended the conduct of the corporation of Londonderry, 1 June. He intervened in discussions on a case of tithes levied on a Catholic priest, 13, 30 Mar., 10 Apr., and got embroiled in a row concerning a Mayo magistrate, 3 Apr. He voted against the government amendment to the Irish arrears of tithes bill, 9 Apr., but for its general tithes bill, 13 July, and against an amendment to this measure, 1 Aug. He divided against the second reading of the Irish reform bill, 25 May, and to preserve the rights of freemen under it, 2 July, commenting on its details, 9, 25 July. He condemned the Irish party processions bill as unworkable and voted against it, 25 June. He sided with opposition against the Russian-Dutch loan, 26 Jan., 12 July. He voted against making the ecclesiastical courts bill retrospective, 3 Aug. Like his colleague he was thought likely to join the Protestant Conservative Society of Ireland that summer.
